kgroundf'l'heory the equations developed for projectile motion to determine flight time based on ht of launch of the projectile. Also. given the time of flight and range, how could one ermine the launch speed of the projectile? othesis the equations and kinematic concepts you developed in your theory to help you .e a hypothesis that answers the questions posed. Your hypothesis should basically J verify the equations that describe Range as a function of Height and Range as a tion of time (both of these equations will involve the horizontal launch speed vi)
